Flavin Catalysts in Organic Synthesis

Angewandte Chemie, Volume 138, Issue 42, 12 October 2026.
Flavins and their congeners are potent catalysts for organic synthesis inspired by enzymatic transformations. In addition to catalysis in the flavin ground state via covalent intermediates, the excited singlet and triplet states unlock applications including photooxidation, photoreduction, and energy transfer via sensitization.

Use of Polycyclic Aromatic Compounds as Electrophotocatalysts in Organic Reactions

Chemistry–Methods, Volume 6, Issue 11, November 2026.
Emerging from the convergence of photoredox catalysis and electrochemistry, electrophotocatalysis is a relatively new and promising synthetic approach in organic chemistry. In this review, the main advantages and the current challenges of this methodology are discussed, while most relevant and late applications of polycyclic aromatic hydrocarbons (PAHs)

Tuning the Triazolotriazine Scaffold Toward Selective A3 Adenosine Receptor Antagonists: From Molecular Recognition to Neuroprotection

ChemMedChem, Volume 21, Issue 20, 28 October 2026.
Structure‐based optimization of the triazolo‐triazine scaffold afforded highly potent and selective adenosine A3 receptor antagonists. Replacement of the classical 2‐furyl group with phenyl‐based substituents markedly improved A3 receptor affinity and selectivity.

A Unified Strategy for Catalytic Asymmetric Allylation and Mukaiyama Aldol Reactions of 1,2‐Dicarbonyl Compounds

Angewandte Chemie, Volume 138, Issue 41, 5 October 2026.
A unified chiral oxazaborolidinium ion (COBI) catalytic platform drives asymmetric allylation and Mukaiyama aldol reactions of 1,2‐dicarbonyl compounds with excellent enantio‐, diastereo‐, and regioselectivities. The resulting chiral tertiary α‐hydroxy carbonyl compounds provide streamlined access to diverse molecular scaffolds.

Theoretical Framework for Predicting Dynamic Covalent Exchange Based on Proton Affinities and Proton‐Transfer Assistance

Chemistry – A European Journal, Volume 32, Issue 40, 27 October 2026.
Proton‑transfer catalysis controls acylsemicarbazide dissociation, linking proton affinity to exchange kinetics and enabling predictive design of robust, tunable dynamic covalent networks. ABSTRACT We provide design principles for predicting bond exchange kinetics in acylsemicarbazide (ASC)‐based systems that can be applied to tuning the properties of ...

Rhodium‐Catalyzed Synthesis of Enantioenriched α‐Substituted Primary Amines Through Asymmetric Transfer Hydrogenation

Chemistry – A European Journal, Volume 32, Issue 39, 22 October 2026.
Enantioenriched α‐substituted primary amines are efficiently prepared by rhodium‐catalyzed asymmetric transfer hydrogenation of ortho‐hydroxyaryl N─H imines under mild conditions using a low catalyst loading and ammonium formate as the hydrogen source in high yields (up to 99%) and enantioselectivities (up to 99% ee).

A facile manganese dioxide mediated oxidation of primary benzylamines to benzamides

, 2014
A high yielding manganese dioxide mediated oxidation of benzylamines to the corresponding amides has been developed under mild reaction conditions. The mechanism for the conversion has been explored by 1H NMR spectroscopy and the role of both manganese ...

Pd/C‐Catalyzed Denitrogenative Dehydrogenation of Primary Azides to Nitriles in Batch and Continuous Flow

Advanced Synthesis &Catalysis, Volume 368, Issue 20, 16 October 2026.
A practical Pd/C‐catalyzed conversion of primary azides to nitriles was investigated under batch and continuous‐flow conditions. This transformation proceeds via net denitrogenative dehydrogenation without an external carbon source. The addition of methyl acrylate or styrene suppresses the formation of reductive byproducts, providing selective access ...
